AUTOMATIC COPYING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 7,073, datecl October 21, 1884:.

Application filed October .23, 1883. (X0 model.)

To all whom it may concern Be it known that I, llIARTIN .T. SUNDERLIN,

of Vatkins, in the county of Schuyler, in the.

impression from the original writing or delineation and reproducing said impression on paper brought in contact therewith.

The object of this invention is to provide simple, convenient, and efficient means for producing copies, as aforesaid, in a convenient, expeditious, and accurate manner; and to that end it consists in the construction and combination of mechanisms, as hereinafter fully described, and specifically set forth in the claims.

The invention is fully illustrated in the annexed drawings, wherein Figures I, II, and III are side elevations showing the copyingmachine in its different operative positions. Fig. 1V is a vertical. longitudinal section of the maehine with the copying-cylinder in position for being cleaned and deprived of the impression. Fig. V is an end view of the same, with the cylinder in position for producing copies. Fig. VI is a plan view of the same. Fig. VII is an enlarged inverted plan view of the device for scraping and cleaning the copying cylinder. Fig. \"III is a detail view of the detachable connection of the cylinder with the standards of the machine, and Fig. IX is an enlarged detached plan view of the paper holder.

Similar letters of reference indicate corre spondi ng parts.

A represents the main supporting-frame of the copyingunachine, from opposite sides of which frame rise two semicircular plates, PP, in the center of each of which is pivoted one of the standards 0 0. These standards are provided with a set-screw, t, by which they are clamped on the plates 1 in any desired position.

C denotes the rotary copying or impression cylinder, consisting of a wooden or other rigid core enveloped in a cylindrical cover of gelatinous substance, which latter I prefer to form of a compound of about one part of fish-glue and common gelatine in equal proportions, one part of water, and three and one-half parts of glycerine, the proportions to be varied according to the temperature of the air. This cylinder is provided at. opposite ends with trunnions, by which it is mounted on the standards 0 O. In order to admit of a ready removal of said cylinder when required to be renewed, I provide the standards with a lateral opening, a, at the journal-bearing and place over the trunnions a plate, 1), having a longitudinal slot, p, through which passes a set-screw, s, by which said plate is adjustably secured to the standard. By slackening the sctscrew s the plate 1) can be raised off from the trunnions of the cylinder suflicient-ly to allow it to be raised out of its bearing and out of the opening a. A crank is connected to one of the trunnions of the cylinder for rotating the latter.

13 represents an oscillatory bed pivoted on the frame A parallel with the axis of the cylinder C, and sustained yieldingly in an inclined position by means of elastic bands I) b, which are attached to the foot of the bed B, and extended rearward under a roller, 0, ar-

ranged across the base of. the frame A, and

thence pass through buckles d, attached to the rear end of the frame. The connection of the bands I) b with the buckles affords simple, convenient, and efi'ective means for adjusting the tension of the said bands. The upper portion of the bed is thus held yieldingly toward the cylinder (1, its approach to thecylinder being limited by the encounter of the foot of the bed with the roller 0, aforesaid, which is thus made to serve as a stop or barrier for limiting the movement of the bed.

1) represents the paper-holder, consisting of a frame which is mounted movably on the bed 13, and is guided in its movement by parallel ways or ilanges on the bed at right angles to the axis of the cylinder,,in which direction the paper-holder is designed to move. The foot of the paper-holder is provided with suitable means for fastening thereto the usual glued end of "a block or pad of writingpaper, or a number of single sheets of writing-paper,

the free ends of whichlie toward the upper end of the paper-holder, for the purpose hereinafter explained The means for fastening the paper to the holder is in this case represented in the form of a string, 6, which passes through the lower end of the paper and is fastened to the back of the holder, as illustrated in Fig. IV of the drawings. I do not, however, limit myself to such means of attaching the paper, as it is obvious that the same admits of many 1nodiiications. The bed B is provided with a longitudinal slot, 1, through which passes the shank of a set-screw, g, which enters a socket on the back of the paper-holder, and is provided with a manipulating-head at the back of the bed, as shown in Fig. IV of the drawings. Said set-screw serves to retain the paper-holder on the bed during its movement thereon, and by tightening it the paper-holder can be confined in its position while replenishing it with paper. To the foot of the bed is secured a cushioned stop, h, to arrest the descent of the paper-holder. A roller, 1', is extended acrossthe lower end of the paperholder, and is pivoted to the sides thereof, which roller is carried under the cylinder 0 after the paper-holder has traversed its entire length upward on the bed B, as hereinafter more fully described. Said roller being capable of rotating with the cylinder relieves the latter of undue abrasion.

K is a cam-disk attached to the end of the cylinder 0, and Z is a lever or push-bar con nected to the side of the bed B and adapted to engage by its free end the shoulder-of the cam K, as illustrated by full lines in Fig. II of the drawings. IVhen the standards 0 are set to bring the cylinder 0 to operate on the paper attached to the paper-holder D, the pnshbar Zlies upon the cam-disk K and slides freely thereon, while the cylinder is rotated in the direction indicated by arrows in Fig. I of the drawings. A reverse movement of the cylinder causes the cam-shoulder to push on the push-bar, and thereby throws the bed B, together with the paper-holder, away from the cylinder 0, as represented by full lines in Fig. II of the drawings. This thrust of the bed B is made adjustable by providing the push-bar I at different points of its length with series of holes for the reception of thepin or bolt by which it is connected to the bed B. This allows the push-bar to be made to project a greater or less distance from the bed The operation of the described machine in copying writings is as follows: The paperholder D, with a block or number of sheets of writing paper secured thereto, being fastened to the upper portion of the bed B by the clampscrew g, the original writing to be copied, made with any of the aniline or transfer inks on a sheet of paper, is laid smoothly upon the block or sheets of paper upon the paper-holder D, with the writing to be copied toward the copying-cylinder O, and is fastened at its lower end to the top sheet of the block or sheets of.

paper by mueilage, or in any other convenient manner. The standards 0 are then loosened from the plates P and swung toward the paper-holder, and before bringing the copying-cylinder in contact with the original writing aforesaid the cylinder is turned to bring the cam K into engagement with thepush-ba-r Z, and the standards 0 are clamped on the plate I. The set-serew r of the paper-holder is then loosened by a slight reverse movement of the cylinder 0. The lever or push-barl being engaged with the cam K throws the vibratory bed B away from the cylinder C, and this allows the'paper-holder I) to descend to the foot of the inclinedvibratory bed B. Then by rotating the cylinder in the direction of the arrows in Fig. I of the drawings the cam K releases the push-bar Z and allows the paper-holder D, resting upon the vibratory bed B, automatically to approach the cylinder, and the original writing resting on the paper upon the paper-holder I) is brought in contact at its top end with the copying-cylinder and pressed against it. The adhesion of the gelatinous face of the cylinder 0 on the paper thus fastened to the paper'holder 1) causes the latter tobe drawn its entire length upon the bed B, the sheet containing the original writing adhering to the cylinder. After the lapse of about a minute the paper containing the original writing is removed from the cylinder, when the greater portion of the ink will be found to be retained on the surface of the cylinder in clear and distinct lines, an exact counterpart of the original writing. The rotation of the cylinder is then continued in the direction of the arrows until the lever or push-bar I again drops into and engages the earn K, when the movement is slightly reversed again, the paper-holder D again doscends to the foot of the vibratory bed B, and by moving the cylinder forward in the direction of the arrows the push-bar is again released from the cam K and the top sheet of paper on the paper-holder D is automatically brought in contact with and pressed against the cylinder at the same point at which the original writing came in contact with it, and by rotating the cylinder in the same way as before in the direction of the arrows the adhesion of the cylinder to the paper causes the paper holder 1) to again traverse the entire length of the vibratory bed B, the top sheet of paper adhering to the cylinder and receiving an impression of the ink-marks of the same in fac-siniile to the original writing. By taking hold of the end of the sheet of paper it can be readily drawn off the cylinder, and in the same manner each succeeding sheet upon the paper-holder is made to receive a copy until the desired number is obtained. It is at the end of each upward movement of the paper-holder that the roller 2 performs its function. The paper-holder having moved from under the cylinder, it becomes support- ICO ed above the cylinder by the roller 2' bearing thereon; and since said roller is capable of rotating with the cylinder the danger of abrading or injuring the gelatinous surface of the cylinder is obviated.

IVhen it is desired to place a new supply of paper on the paper-holder, the latter is raised to the upper end of the bed B, and the setscrew g is tightened to retain the paper-holder in said position, then a new block or quantity of writing-paper can be seen red thereon.

Inasmuch as it is essential to remove the ink from the gelatinous cylinder as soon as possi* ble after the copying process, I connect to the supporting fraine A a cleaning apparatus in such relative position as to allow the aforesaid cylinder to be readily carried thereto. This cleaning apparatus consists of a water trough or receptacle, T, secured to the frame A, between the plates P P, at the end opposite that to which the bedB is connected. In this trough is placed longitudinally a skeleton frame, U, to the top of which is fastened a perforated metallic sheet, V. By loosening the standards 0 on the platesP the cylinder 0 can be carried over into the trough Tand laid onto the perforated sheet V; then by revolving the cylinder 0 the sheet V is caused to erase the ink-marks from the surface of the cylinderin a very expeditious, convenient, and effective manner.

Persons conversant with the use of gelatinous beds l'or copying writings will appreciate the advantages of the before'described copying apparatus. The copies being produced in the most expeditious manner prevents theink from penetrating the gelatinous surface as deep as it generally does the ordinary flat gelatinous bed; hence it is more readily erased and the cylinder correspondingly preserved.
